  POM為白色一般不透明，著色性好， 比重1.41-1.43克/立方厘米，成型收縮率1.2-3.0%，成型溫度170-200℃ ，干燥條件80-90℃ 2小時。POM的長期耐熱性能不高，但短期可達到160℃，其中均聚POM短期耐熱比共聚POM高10℃以上，但長期耐熱共聚POM反而比均聚POM高10℃左右。可在-40℃～100℃溫度范圍內長期使用。POM極易分解，分解溫度為240度。分解時有刺激性和腐蝕性氣體發生，故模具鋼材宜選用耐腐蝕性的材料制作。

（1）POM是結晶型塑料,密度為1.42g/cm3,它的鋼性很好,俗稱“賽鋼”.
　　（2）它具有耐疲勞、耐蠕變、耐磨、耐熱、耐沖擊等優良的性能,且摩擦系數小,自潤滑性好.
　　（3）POM不易吸濕,吸水率為0.22～0.25%,在潮濕的環境中尺寸穩定性好,其收縮率為2.1%(較大),注塑時尺寸較難控制,熱變形溫度為172℃
 
   POM強度、剛度高，彈性好，減磨耐磨性好。其力學性能優異，比強度可達50.5MPa，比剛度可達2650MPa，與金屬十分接近。POM的力學性能隨溫度變化小，共聚POM比均聚POM的變化稍大一點。POM的沖擊強度較高，但常規沖擊不及ABS和PC；POM對缺口敏感，有缺口可使沖擊強度下降90%之多。POM的疲勞強度十分突出，10交變載荷作用后，疲勞強度可達35MPa，而PA和PC僅為28MPa。POM的蠕變性與PA相似，在20℃、21MPa、3000h時僅為2.3%，而且受溫度的影響很小。POM的摩擦因數小，耐磨性好（POM>PA66>PA6>ABS>HPVC>PS>PC），極限PV值很大，自潤滑性好。POM制品對磨時，高載荷作用時易產生類似尖叫的噪聲。

   POM的電絕緣性較好，幾乎不受溫度和濕度的影響；介電常數和介電損耗在很寬的溫度、濕度和頻率范圍內變化很小；耐電弧性極好，并可在高溫下保持。POM的介電強度與厚度有關，厚度0.127mm時為82.7kV/mm，厚度為1.88mm時為23.6kV/mm。
環境性能

POM不耐強堿和氧化劑，對烯酸及弱酸有一定的穩定性。POM的耐溶劑性良好，可耐烴類、醇類、醛類、醚類、汽油、潤滑油及弱堿等，并可在高溫下保持相當的化學穩定性。吸水性小，尺寸穩定性好。
POM的耐候性不好，長期在紫外線作用下，力學性能下降，表面發生粉化和龜裂。

⒈增強POM
主要增強材料為玻璃纖維、玻璃球或碳纖維等，并且玻璃纖維常用，增強后的力學性能可提高2～3倍，熱變形溫度提高50℃以上。
⒉高潤滑POM
在POM中加入石墨、F4、二硫化鉬、潤滑油及低分子量PE等，可提高其潤滑性能。例如，在POM中加入5份F4，可降低摩擦因數60%，耐磨性提高1～2倍。再如，在POM中加入液體潤滑油，可大幅度提高耐磨性和極限PV值

POM又稱賽鋼、特鋼。它是聚合所得。POM-H，POM-K是高密度、高結晶度的熱塑性工程塑料。具有良好的物理、機械和化學性能，尤其是有優異的耐摩擦性能。

POM是一種表面光滑，有光澤的硬而致密的材料，淡黃或白色，可在-40- 100°C溫度范圍內長期使用。它的耐磨性和自潤滑性也比絕大多數工程塑料優越，又有良好的耐油，耐過氧化物性能。很不耐酸，不耐強堿和不耐紫外線的輻射。(加入UV劑，能大大提高其耐紫外線等級）
